Differences between Pull and Push Publishing

Introduction

We provide two types of CDN Live services - with Pull and
Push Publishing.
Here is a short overview of differences between them.

CDN Live services with Pull Publishing (via your streaming server)

Origin (source) stream - is a live stream published via your streaming server on
Origin URL over
RTMP protocol in MP4 or FLV container format and
encoded with H.264 video codec and AAC or MP3 audio codec.
You can use Pull Publishing if you have your own streaming server, e.g. Wowza or Adobe FMS.

CDN Live services with Push Publishing (via your live encoder)

Origin (source) stream -
is an output from your live encoder such as
Adobe Flash Media Live Encoder,
Telestream Wirecast or
Open Broadcaster
connected to CDNsun streaming server (CDN service Origin PoP).
Please note that the output from your live encoder has to be in
MP4 or FLV container format and encoded with H.264 video codec and AAC or MP3 audio codec.

Please note that both traffic 2. → 3. and traffic 3. → 4. are being charged.
Also please note that if there are 100 viewers then
there are 100 connections 3. → 4. but only 1 connection 2. → 3 (assuming
that all viewers are watching via the same streaming protocol, e.g. RTMP).
